A system where you don´t need a radio to talk on the radio , Basically you can use you pc as you transmitter , your voice travels over the internet then is broadcast at the gatway to a recieving station. Again , problem is the avalibility of the internet at the recieving end etc. but this would work crossboarder i imagine. Think no internet in the usa but access in mexico. Anyone along the mexican boarder could use a handheld to connect to an access point in mexico a few miles away, then dial in the where they want to come out.

There are handeld radios out there that are licence free the PMR446 band comes to mind but these are basically toys, and range is limited to a mile at most.

Here is a ham emergency network

http://www.iresc.org/

and this system , but would they switch the servers off? http://www.winlink.org/node/12

The Winlink 2000 system is a "star" based network containing 3 mirror image, redundant COMMON MESSAGE SERVERS (CMS), one in San Diego, one in Detroit and one in Perth, Australia. These ensure that the system will remain in operation should any chunk of the Internet become inoperative. Each Radio Message Server node (RMS) is tied together as would be the ends of a spoke on a wheel with the hubbing being done by the Common Message Servers. Traffic goes in and out between the CMS and the Internet email recipient, and between the end users and the Radio Message Server gateways. Multiple Radio-to-Radio addresses may be mixed with radio-to-internet e-mail addresses, allowing complete flexibility.
